Rotozip Tile Cutting Bit, 1/8" Drill Bit Diameter, 33,000 RPM Max. Speed, 1/8" Shank Diameter, PK 4

Routing bits work with cut-out tools to cut drywall and other materials. They look like and spin like twist drill bits but cut with their sides. They are used to cut along a straightedge, make curved freehand cuts, and trace the shape of electrical boxes, panels, and frames to make cutouts. The bits fit into a collet in the cut-out tool's spindle. Bits with a cutting tip have a sharp point for drilling into and cutting through material. They are typically used when cutting off lengths of material. Bits with a noncutting tip have a smooth, dull end (also called a guidepoint) that rides a box, panel, or frame without cutting into it. They reduce the risk of damage to underlying surfaces or objects behind the material being cut.
